Social distancing is not a new concept in the natural world，where infectious diseases are commonplace.Through specialized senses animals can detect certain diseases and change their behavior to avoid getting ill.
In 1966，while studying chimps（猩猩）in a Tanzanian national park，zoologist Jane Goodall observed a chimp named McGregor who had caught a highly infectious virus.His fellow chimps attacked him and threw him out of the troop.In one instance，McGregor approached chimps in a tree.He reached out a hand in greeting，but the others moved away without a backward glance.
"For a full two minutes，old McGregor sat motionless，staring after them，" Goodall notes in her 1971 book In the Shadow of Man. "It's really not that different to how some societies react today to such a tragedy."
Not all animals are so aggressive toward their ailing neighbors.Sometimes it's as simple as avoiding those who may infect you.
When Kiesecker，a lead scientist in America，studied American bullfrog in the late 1990s，he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs，but healthy members actively avoided those that were sick.Bullfrogs rely on chemicals signals to determine who is sick or not.
Caribbean lobsters also shun diseased members of their community，well before they become infectious.It takes about eight weeks for lobsters infected with the deadly virus Panulirus argus mininuceovirus to become dangerous to others.Normally social animals，lobsters begin keeping away from the diseased as early as four weeks after infection - once the lobsters can smell certain chemicals released by sick individuals.
"Overall，it's important to note that，unlike us，animals don't realize if they stay home，they might actually reduce the infection rate，" Kiesecker explains. "As humans，we have that abiljye.aiy.It's a big difference."

2．A few weeks ago，I sat with a California farmer named Dave Ribeiro．I asked him what he wished to know about farmers．He smiled and said， "That we walk among you．We look like you and talk like you．We have advanced degrees and hobbies，just like you．"
Take Dave for example：He's a young man with a music degree．And if you walked past him on the street，you'd never think， "There goes a farmer．"
Is someone like Dave who you picture when you think of a farmer？Probably not．I think that most people would picture a man in his overalls（工作服）．I can tell you，that does not represent Dave or any of the many other farmers I have gotten to know．
Not only do we have to throw out our previous impression of farmers，but farming as a whole doesn't look much like it used to either．We recently sent a team out to see what modern farming looks like，and they found farmers to be completely different from our usual ideas about them and also came across them in some unexpected places．
In a parking lot in a neighborhood of Brooklyn，they met a new crop of young farmers who were trying to bring fresh greens closer to eaters in the city by growing them in high-tech indoor vertical（垂直的） farms．In a Florida field under the fight path of an airport，they discovered farmers with university degrees growing plants that might someday fuel our cars．And in a modern farm in California，they observed how farmers were using technology to take the best possible care of their animals．
These farmers all spend their days in very different ways-none of them looks like the previous farmer we have in our mind-but they're all working on new ways to feed our planet．Not only do we need to change our idea of what farming looks like，but we also need to change our view of where solutions can come from．Feeding all of us is going to take all of us working together．
（1）How does Dave describe today's farmers？
A．They often walk on the street．
B．They are leading a very busy life．
C．They are similar to ordinary people．
D．They have little time to make friends．
（2）How does the author think most people see farmers？
A．They usually wear overalls．
B．They have interesting hobbies．
C．They are skilled at growing crops．
D．They know modern farming practices．
（3）What was the purpose of the team？
A．To deepen connections among farmers．
B．To study different technologies in farming．
C．To find the new developments of modern farming．
D．To encourage farmers to use new farming method．
（4）What do the farmers mentioned in Paragraph 5 have in common？
A．They all work in the city．
B．They all use high technology．
C．They all do hard physical work．
D．They all work with universities．發(fā)布：2025/1/1 18:0:1組卷：26引用：5難度：0.7 -
3．Your child is unique，but what all children have in common is natural curiosity and an ability to learn they are born with.Our brains are active all the time，and a baby's brain is the busiest of all.Research has shown that babies begin to understand language about twice as fast as they actually speak it.By showing children other languages at an early age，you are giving them the opportunity to make use of their natural ability to hear and recognize between the sounds of other languages，and their ability to make sense of what they are hearing.
Communication is something that children do to help them achieve something else，and they are unaware of the large amount of learning taking place.They take everything in through their senses，making connections between what they hear，see，smell，taste and touch.As long as we provide the right conditions，their learning and development will take place in a natural way.
In your child's early years，the emotional environment is just as important as the physical environment.Children learn when they feel safe，happy，valued and listened to.This is central to any learning experience in a child's early years，including learning an additional language.Your child has a trial-and-error approach to its development，and making mistakes is a valuable part of the learning process.When children learn an additional language at an early age，they get the benefits of experimenting with that language as a natural part of their development.Their progress isn't prevented by a fear of getting it wrong，and very young children are simply working their way towards getting it right.
The long-term benefits of learning another language go beyond being able to communicate with others.Studies suggest that children learning an additional language tend to score better on standardized tests because learning languages develops listening，observation，problem-solving and critical （批判性的） thinking skills.These are skills that are of life-long benefit，both personally and professionally.Encouraging in children a love of language at an early age prepares them well for school and for life.

A．a(chǎn)re in bad emotion

（4）In fact learning another language helps children to.
A．take more tests

C．encourage themselves
D．develop life-long skills發(fā)布：2025/1/1 17:30:2組卷：4引用：3難度：0.5
